I am emailing a link of this to everyone on the class list every Wednesday morning. If you are not receiving these emails or want to have them sent to another email address feel free to email me at jippo@campus.ie and I will add you to the mailing list.

## These Weeks

In lectures, we finished off the notes.

## Review Week

I will hold a tutorial on Tuesday at the same time and place. I should have the results of Test 2 by then.

## Appraisal

Thank you very much for your work on the appraisal. Sorry about all the hairstyles.

## Problems

You need to do exercises – all of the following you should be able to attempt.

When asked to find the critical points of a function defined on the entire real line (rather than just on a closed interval $[a,b]$), the ‘endpoints’, $\pm\infty$ are not considered critical points.

Finding the limit as $x\rightarrow\pm\infty$ means find an asymptotic.

‘Horizontal’ asymptotes are asymptotics.

Convex is concave up and concave is concave down.

Do as many as you can/ want in the following order of most beneficial:

$\lim_{x\rightarrow 2}\left(\frac{3x^2-2x+2}{x^2-x-2}\right)=\pm\infty$.

2. First example in section 4.7.
